ADDING uecnnm I Application filed July 8,

To all whom it may concern:

Be it known that I, PAUL BIALIK, a citizen of the United States of America, a resident of Eagle Park, in the county of Madi son, State of Illinois, have invented certain new and useful Improvements in Addin Machines. of which the following is a ant, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates generally to improvements in adding machines, and particularly to an adding machine of simple and inexpensive construction, the machine being of the type wherein there is a series of numeral wheel mechanisms and a separate actuating device for each numeral wheel mechanism, means being provided for carrying from one numeral wheel mechanism to the next adjacent numeral wheel mechanism.

With the foregoing and other objects in view, the invention comprises the novel construction, combination and arrangement of parts hereinafter more specifically described and illustrated in the accompanying drawings wherein is shown the preferred embodiment of'the invention. However, it is to he understood that the invention comprehends changes, variations and modifications which come within the scope of the claims hereunto appended.

Fig. 1 is a plan view of my adding machine.

Fig. 2 is a fragmentary section on line 2-2 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 1.

Fig. 4 is a fragmentary section on line 4 1: of Fig. 1.

Fig. 5 is a vertical section through the mechanism shown in Fig. 4.

In the accompanying drawings, A designates the base of the machine which is preferably rectangular in shape and is provided, at its approximate center, with a stationary vertical post B. Mounted on the post B and adapted to rotate thereabout are a plurality of disks 1, each of which is provided with a pluralit of upwardly ex tending projections 2. T e disks 1 are preferably formed of sheet metal and the projections are formed by cutting semicircular slits in the disks and bending the metal within said semicircular slits upwardly.

1822. Serial No. 572,549.

Each of the disks 1 is provided with a comparatively thick disk of metal 3 which is coated on its upper face, the purpose of said last mentioned disks being to separate the disks 1 so that any one thereof may be manipulated without lnterference from the others. Located between each pair of disks 1 and below the lowermost disk 1 is a stationary spacing disk 4, said spacing disk: belng of the approximate shape of the disks 1 and being provided with tongues 5 which extend from the peripheral edges of said disks. 'As shown in Fig. 2 of the drawings. the tongues 5 formed on the stationary disks 4 extend upwardly from said disks and their upper portions and are bent horizontal. Secured to the upper face of the base A is an anchor member 6, said anchor member having a horizontal portion which rests on the upper face of the base A, an upwardly extending portion and an upper horizontal portion which is located immediately above the horizontal portions of the tongues 5. Embracing the marginal portions of the upper horizontal portion of the anchor member 6 and the marginal portions of the horizontal portions of the tongues 5 is a plurality of U-shaped clips 7 which clamp the tongues 5 to the anchor member 6 whereby the disks 4 will not be rotated by the friction of the rotating disks 1. To give additional strength to the bank of disks already described, I provide a brace 8, one end of which is secured to the top face of the base A and the other end of which is secured to a stationary disk 9 located above the uppermost rotatable diskl.

10 designates a numeral wheel shaft extending radially of the disks 1, said shaft being non-rotatabl journaled in a bearing 11 secured to the base A and a bearing 12 secured to the disk 9. Loosely mounted on the shaft 10 is a plurality of numeral wheels 13, spaced apart by spacing sleeves 13, said wheels being capable of independent rotation on said shaft 10. Each of the numeral would be likewise rotated due to the fact that the projections 2 on the. disk and the toothed wheel 14 on the numeral wheel are inmesh.

The device illustrated in the drawings is provided with four numeral wheels, namely, units, tens, hundreds and thousands, and all of said numeral wheels except the units wheel, which is the wheel closest to the outside of the machine, project over the toothed portion of the disk which actuates the numeral wheel of the next higher order and the toothed wheels 15, already mentioned, are mounted on said projecting portion.

Formed on each of the actuating disks 1 in such position that they'will engage a toothed wheel 15 is a plurality of carrying tongues 16, which like the projections 2 are stamped from the body of the disk and project upwardly therefrom. On each actuating disk 1 there is a carrying tongue 16 opposite every tenth projection.

The operation of my device is as follows:

Assuming that the zero on each of the numeral wheels is in the reading position and it is desired to add the following column of figures:

The projection on the actuating disk 1 which operates the hundreds numeral wheel opposite the figure 4 on the disks 4 will be engaged by the finger of the operator, and

said actuating disk will be rotated until said projection is adjacent to the brace 8, which distance will be sufiicient to bring the numeral 4 on the associated numeral wheel to the reading position on said numeral wheel. The actuating disk 1 which operates the tens numeral wheel is then rotated until the numeral 5 on the associated numeral wheel is in the reading position on said numeral wheel, and the disk which operates the units numeral wheel is then operated sufiiciently to bring the numeral 6 into the reading position. The second number, namely, 37 5, would be added to the 456 already in the machine in the manner just described, the disk 1 controlling the hundreds numeral wheel being rotated a suflicient distance to bring a projection 2 from a point opposite the numerals 3 on the disks 4 to a point adjacent to the brace 8, whereby the numeral 7 would be in the reading position on the hundreds numeral wheel. The actuating disk 1 controlling the tens numeral wheel would be rotated, in the manner described, a sufiicient distance to cause the seventh numeral after the 5, which is showing, to be brought to the reading position on the numeral wheel, which seventh numeral is the 2. As the disk 1 controlling the tens numeral wheel was being rotated, one of the carrying tongues came in contact with the toothed wheel 15 mounted on the hundreds numeral wheel and rotated said wheel of a revolution, thereby bringing. the 8 into the readin The disk 1 controlling the units numeral wheel is then rotated a suflicient distance to bring the fifth numeral on said numeral wheel, after the 6 already showing, which numeral is the 1, and in this case also a carrying tongue contacted with the toothed wheel 15 on the tens numeral wheel and rotated said tens numeral wheel sufficiently to cause the next successive numeral to be exhibited, which numeral is the 3. the result of the addition of the two members mentioned will appear on the numeral wheels as 831.

To return the numeral wheels 13 to a position so that the O is in the reading position onv each of said numeral wheels, I provide a handle H which is rotatably mounted on the vertical post B, said handle comprising an elongated collar 18 which surrounds the upper portion of said post 13, said collar having an enlarged upper portion provided with a pair of ears 19. Located between the ears 19 and pivotally attached thereto is an arm 20 provided with a plurality of downwardly. extending projections 21. Formed on the enlarged portion of the elongated collar 18 is a downwardly extending lug 22, and formed on the lower edge of the arm 20 is a similar lug 23. An expansible coil s ring 24 is located between the lugs 22 an 23, the tendency of said spring being to raise the outer end of the arm 20 as shown in full lines in Fig. 3 of the drawings. Located on the top face of the base A is a stop 25 for limiting the forward movement of the arm 20.

When the zero on each of the numeral wheels is in the reading position, one of the carryingdetents 16 on each of the disks 1 is in alinement with the stop 25, as shown in Fig. 1 of the drawings. Assume now that the device has been actuated and it is do sired to bring all of the zeros on the numeral wheels to the reading position; the arm 20 will be depressed and said arm will be oscillated from its normal position adjacent to the stop 26 in the direction toward the stop 25. A carrying tongue 16 on each of the disks 1 will be in the path of the moving projections 21, and as each tongue is en aged the disk on which it is former! will be rotated, so that when the arm 20 strikes the stop 25 a tongue on each of the disks will be in alinement with said stop and the zeros will be in the reading position on the numeral wheels.

While I have shown and described an adding machine having but four actuating disks and numeral Wheels, it is, of course, apparent position on said numeral wheel.

Hence that the capacity of the machine may be mcreased by utilizing a greater number of actuating disks and numeral wheels.

wheels being arranged immediately above said disks and said toothed wheels and the teeth on said disks being adapted to mesh whereby the rotation of one of said disks will impart a like rotation to the associated numeral wheel.

2. An adding machine comprising a plurality of rotatable disks provided with teeth,

said disks being of varying diameters and being arranged one above the other, a shaft arranged above and radially of said disks, a plurality of numeral wheels mounted on said shaft, and toothed wheels on said numeral wheels, said numeral wheels being arranged immediately above said disks and said toothed wheels and the teeth on said disks being adapted to mesh whereby the rotation of said disks will impart like rotation to the associated numeral wheels.

3. An adding machine comprising a plurality of rotatable disks of varying diameters arranged one above the other, a plurality of numeral wheels, one of which is associated with each of said rotatable disks, means on said rotatable disks cooperating with means on said numeral wheels whereby rotation of said disks will actuate said numeral wheels, and carrying means comprising projections on said disks adapted to engage means associated with said numeral wheels whereby motion may be transmitted from said rotatable disks to adjacent numeral wheels.

4. An adding machine comprising a plurality of rotatable disks provided with teeth, a plurality of numeral wheels, one of which is associated with each of said rotatable disks, a toothed wheel on each of said numeral wheels adapted to mesh with the teeth on one of said rotatable disks, a second toothed wheel on each of said numeral wheels, and carrying means on said disks adapted to engage the second mentioned toothed wheel on an adjacent numeral wheel whereby motion may be transmitted from said rotatable disks to said adjacent numeral wheels. 1

5. An adding machine comprising a plurality of rotatable disks provided with teeth, a plurality of numeral wheels, one of which is associated with each of said rotatable disks, a toothed wheel on each of said numeral wheels adapted to mesh with the teeth on one of said rotatable disks, a second toothed wheel on each of said numeral wheels,and carrying means comprising projections on said disks adapted to engage the vsecond mentioned toothed wheel on an adjacent numeral wheel whereby motion may be transmitted from said rotatable disks to said adjacent numeral wheels.

In testimony that I claim the foregoing I hereunto afiix my signature.
